Add Chat Formatting Support For Servers (#1483)

* add chat support for html formatting

* html character serialization, normal color format support

* change for chat input handling on color

has a bug where the text after the cursor gets stripped of its color, need to make a function to backstep on a string and find the last used color codes, or get all color codes used before the string is split, and apply them to the start of the next string

* expose jukebox label as action bar like java

* prevent players from sending chat color

* restore non styled chat size check
